A Four-Door Master Controller That Cascades to Sixteen

The ASC2204C-H controls four doors directly and cascades over CAN bus to sixteen sub-controller modules, holding 200,000 cards and 150,000 records. The cascade is what makes it a site controller rather than a door controller — a campus can be built out from one head end instead of managing a controller per building.

Key Details

• Four doors, expanding to many — Four openings directly, with up to 16 sub-controller modules over CAN bus — so the system grows without replacing the head end.
• 200,000 cards — Capacity for a large site, with 150,000 stored records for audit.
• Multi-factor credentials — Card, password and fingerprint individually or in combination, plus multi-card rules where two people must present to open a door.
• Reader flexibility — Wiegand or RS-485 readers, so existing hardware can usually be retained when upgrading the controller.
• Networked — TCP/IP to the management platform for central administration and reporting.

Where It Fits

For medium and large sites — schools, warehouses, multi-building offices — where doors will be added over time. The multi-card rule is particularly relevant for cash rooms, pharmacy stores and other dual-custody areas.
